enhance support for zgc and shenandoah

[CuiWeiloong]

The latest GCViewer failed to parse some gc events of ZGC and ShenandoahGC. I fixed some bugs and added some gc event types in this PR.

1. The event "Metaspace" in gc tag "[gc,metaspace]" don't match the "PATTERN_MEMORY" rules for ZGC and don't have GC number for Shenandoah, ignored in "DataReaderUnifiedJvmLogging.java:handleTagGcMetaspaceTail()" method.

   // ZGC:
   //  [1.182s][info][gc,metaspace] GC(0) Metaspace: 19M used, 19M capacity, 19M committed, 20M reserved
   //  [1.182s][info][gc,metaspace] GC(0) Metaspace: 11M used, 12M committed, 1088M reserved
   // G1:
   //  [5.537s][info][gc,metaspace] GC(0) Metaspace: 118K(320K)->118K(320K) NonClass: 113K(192K)->113K(192K) Class: 4K(128K)->4K(128K
   // Shenandoah:
   // [5.063s][info][gc,metaspace] Metaspace: 13104K(13376K)->13192K(13440K) NonClass: 1345K(11456K)->11431K(11520K) Class: 1758K(1920K)->1761K(1920K)

2. [gc,heap] -> Unknown gc type for ZGC: Excludes all lines that do not contain Capacity.

   [1.182s][info][gc,metaspace] GC(0) Metaspace: 19M used, 19M capacity, 19M committed, 20M reserved
   [1.182s][info][gc,heap     ] GC(0)                Mark Start          Mark End        Relocate Start      Relocate End           High               Low

   [1.182s][info][gc,heap     ] GC(0)   Garbage:         -               393M (10%)         131M (3%)           13M (0%)             -                  -              
   [1.182s][info][gc,heap     ] GC(0) Reclaimed:         -                  -               262M (7%)          380M (10%)            -                  -              

3. Add new gc events "Concurrent Mark Free,Allocation Stall,Relocation Stall" for ZGC.
4. Update some gc events that contain wrong GcPattern for ShenandoahGC.
5. Add percentiles data to output csv file.
6. Add "[gc,init" to LOG_ONLY_STRINGS.

Please review this PR.

Thanks, Weilong Cui
